Overview

Affected versions of this package are vulnerable to Out-of-Bounds. An out-of-bounds memory write flaw was found in the Linux kernel's joystick devices subsystem in versions before 5.9-rc1, in the way the user calls ioctl JSIOCSBTNMAP.

The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
